Ultrahigh Selectivity HS Gas Sensor Based CsPbBr Perovskites via Pb-S Bonding Interaction.

High selectivity and sensitivity sensing of HS gas play a decisive role in the early detection of sulfide solid-state battery failure. Herein, we construct the CsPbBr perovskite-based sensor that exhibits outstanding gas-sensing performance to HS at room temperature, including high selectivity, fast response/recovery speed (73.5/275.

Recent Advances in Structure Design and Application of Metal Halide Perovskite-Based Gas Sensor.

Metal halide perovskites (MHPs) are emerging gas-sensing materials and have attracted considerable attention in gas sensors due to their unique bandgap structure and tunable optoelectronic properties. The past decade has witnessed significant developments in the gas-sensing field; however, their intrinsic structural instability and ambiguous gas-sensing mechanisms hamper their practical applications. Herein, we summarize the recent advances in MHP-based gas sensors.

Vacancy-assisted exposed Sn atoms enhancing NO room temperature sensing of SnSe nanoflowers.

NO is a hazardous gas extremely harmful to the ecosystem and human health, so effective detection of NO is critical. SnSe is a promising candidate for gas sensors owing to its unique layered configuration that facilitates the diffusion of gas molecules. Here, ultrathin self-assembled nanoflowers F-SnSe rich in defects were synthesized by a simple solvothermal method.

High Response and Selectivity of the SnO Nanobox Gas Sensor for Ethyl Methyl Carbonate Leakage Detection in a Lithium-Ion battery.

It is well-known that metal-oxide semiconductors (MOS) have significant gas sensing activity and are widely used in harmful gas monitoring in various environments. With the rapid development of new energy vehicles, the monitoring of the gas composition and concentration in LIB has become an effective way to avoid safety problems. However, the study of typical electrolyte solvent detection, such as EMC and DMC detection by the MOS sensor, is still in its infancy.
